POTATO SORTER AND GRADER.

SPECIFICATION forming part of Letters Patent No. 725,172, dated April14, 1903.

Application filed July 20, 1901.

To all whom it may concern:

Beit known that LEDWIN TAYLoR,a citizen of the United States,residing atEdwardsville, in the county of Wyandotte and State of Kansas, haveinvented new and useful'Improvements in Potato Sorters and Graders, ofwhich the following is a specification.

My invention relates to a combined potato sorter, grader, and sacker.

The object of my invention is to screen potatoes and to sort two sizesof potatoes at the same time and to sack the potatoes directly after thegrading without further handling.

I will fully describe my invention, with reference to the accompanyingdrawings, in which- Figure l is a side elevation of the device embodyingmy invention, showing the two receiving-sacks. Fig. 2 is a longitudinalvertical section of the same omitting the sacks. Fig. 3 is a plan Viewof a tilting hopper and screens. Fig. 4.- is a transverse section of theI tilting hopper and screens taken on line IV IV of Fig. 2. of thehoppers, their supports being broken away.

The carrying-frame comprises four cornerposts 2, four longitudinal bars3 3 4 4E, bolted to said posts, two oblique braces 5 5, nailed to theposts, two cross-pieces 6 6, connecting the posts, and two uprighttilting hopper-supporting standards 7 7, bolted to bars 3 3 and 4 4. Thebars 3 3 extend beyond the posts 2 at one end of the frame and supporttwo down-spouts 8 and 9, which are fed from the screens, as describedhereinafter. The upper ends of the vertical standards 7 7 are notched toreceive a pivot-rod 12, which extends through holes in the sides of thehopper 13, whereby the hopper is supported piv otally, so that it may beoscillated by the hand. The sides 13 of the hopper are connected at oneend by an end plate 14; and at the opposite end by a cross-plate 15,which terminates below the upper screen 16. Screen 16 is supported bycleats 17, secured to the sides 13, (see also Fig. 4,) and the lowerscreen 18is supported by cleats 19, secured to the sides. The upperscreen is of larger mesh than the lower screen, so that the smallestpotatoes Fig. 5 is an enlarged plan view Serial No. 69,165. (No model.)

fall through the former upon the latter. The lower screen 18 is cut offshorter than the upper screen to give room for the small-potatodown-spouts 9. The ends of the hopper sides 13 adjacent to thedownspouts are made to converge, as shown in Fig. 3, as the screens willprobably be wider than the mouths of the down-spouts. When the hopper isin the position shown in Figs. 1 and 2, the potatoes from screen 16 arereceived by down-spout 8, while those from screen 18 are received bydown-spout 9. Sacks 2 1 are attached to the respective down-spouts toreceive the two grades of potatoes. To sup port the receiving end of thetilting hopper while it is being filled, I prefer to employ two stops 2222, which are nailed to the bars 3 and braces 5, and as said braces passoutside of said bars the upper ends of the stops 22 will be inclinedinwardly or together, thereby terminating under the sides of the hopper13.

In operation the hopper 13 is tipped back to the position shown bydotted lines in Fig. 1 and a suitable quantity of potatoes is dumpedtherein. The tilting hopper is then oscillated back and forth until thepotatoes roll ofi the screens 16 and 18, through the down-spouts, intothe sacks 21, dirt falling through both screens to the ground.

' Having now fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is-- A potatosorter, grader and sacker, the combination of a suitable carrying-frame,the upper longitudinal bars extended, down spouts adapted to engage themouth of sacks supported on the extended ends of said bars, Verticalstandards secured to the supportingframe, a tilting separating-hoppermounted on the vertical standards, one end thereof adapted to engage thedownspouts, substantially as described.

In testimony whereof I affix my signature in the presence of twowitnesses.

EDWIN TAYLOR.
